About this project

sping is a modern, cross-platform network diagnostics CLI written in Rust. It goes beyond traditional ping by combining real-time latency and packet loss monitoring with connection quality scores, gateway/WAN checks and contextual diagnostics. Monitor multiple targets and get clearer insights when network connectivity fails.

sping — Real-Time Network Diagnostics for the Terminal

sping is an open-source, cross-platform network diagnostics tool written in Rust. It brings together traditional ping functionality, live connectivity monitoring and network context to help users understand not just whether a host responds, but what might be happening when connectivity fails.

Designed for sysadmins, network engineers and developers, sping provides real-time measurements, quality scoring and contextual diagnostics in a lightweight terminal interface.

Key Features

Real-Time Monitoring: Track latency, jitter, packet loss, TTL, connection quality, trends and network interruptions as they happen.
Multi-Target Dashboard: Monitor multiple hosts simultaneously in a live terminal view.
Network Context: See which interface and source address are being used, alongside gateway and WAN reachability, to help distinguish local network problems from upstream connectivity issues.
Connection Quality: Get a rolling quality score (0–100, graded A–D) based on recent packet loss and jitter, with trend and spike detection.
ICMP and TCP Probes: Test IPv4/IPv6 connectivity using ICMP, or use TCP connection probes when ICMP is filtered.
On-Demand Diagnostics: The experimental --diagnose mode investigates outages using additional connectivity checks and a bounded traceroute, reporting what could and couldn't be established.
Automation-Friendly: JSON/NDJSON output, batch monitoring and familiar ping-style command-line options.
Cross-Platform: Available for Linux, macOS and Windows.

What's New in Version 1.8.0

Unreachable vs. Timeout: Distinguishes ICMP destination-unreachable responses from ordinary timeouts, identifying the reporting device where supported.
Host Network Information: The new sping --ip option displays local IPv4/IPv6 addresses, interfaces, source addresses and gateway information. Optional --external discovers the address seen by a STUN server.
Persistent Outage Diagnostics: The experimental --diagnose mode now repeats its checks during prolonged outages.
Explicit ICMP Mode: The new --icmp option preserves traditional ICMP probing as the default behavior evolves in future versions.

Example Usage

Monitor multiple destinations:

sping 192.168.1.1 8.8.8.8 google.com

Investigate a connectivity problem:

sping google.com --diagnose

Inspect host network addresses:

sping --ip
